Arrest made in retired Villanova professor's death

PHILADELPHIA—Authorities say they have arrested a Philadelphia man for the stabbing death of a retired Villanova University professor in her apartment this month.

Police say 42-year-old Jose Diaz was charged with murder and related offenses for the death of 69-year-old Carol Ambruster.

The former assistant professor of astronomy and astrophysics was found by her roommate in the kitchen of their apartment in the Germantown section of the city on Dec. 9. She was found with multiple stab wounds to her chest and neck area.

Police say Diaz lives less than a mile from the apartment building where Ambruster was killed.
